OIL-BURNER.

To all whom it may concern:

Be it known that I, THOMAS MUEHQEISEN, a citizen of the United States, residing at San Diego, in the county of San Diegoand State of California, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

My invention relates to a hydro-carbon oil burner adapted to be used for burning stove distillate or kerosene, refined or semirefined;

Specification of Letters Patent. Application filed March a, 1918.,

and the objects of my invention are first; to i provide an oil burner of this class in which the fuel supply is controlled by the gas valve,

1 thus automatically controlling the flow of the its passage to theburner forming it into a gas: third, to provide a new and novelly confuel to the burner relatively to the volume of the fireiseconthto provide an-oil burner of this class with means for heating the fuel in structedbifiner portion for distributing the blaze and fourth: to provide an oil burner of this class which is very simple and economical ofconstruction, durable, easy to install, easy to operate and will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, conibination'and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying Patented A r. 1, 1919. Serial No. 220,701.

mixer 2, shaped asshown best inFigs. 1 and 2 of the drawings. The extendedend of this tube 1 is beveled at 1 of the proper shape to provide exit of the gas properly and said strikes against the super mixer 2 and rebounds, thus more thoroughly mixing the same. This tube 1 is also provided with a plurality of fine slots 1 adapted to permit a. small portion of the gas to pass out therethrough where it burns on the outside and over these slots is a screen 1 adapted to further inixthe gas passing therethrough and also" prevent backfiring into the tube land wound around this tube 1 over the slots 1 is the coil l thus providing means for heating the coil 4, thus reducing the fuel to a gas in drawings and to the characters of reference thereon which form a part of this specification, in which -Figure 1 is a plan view of my burner with the blaze distributing portion removed. Fig. 2 is a longitudinal sectional view thereof, showing parts in elevation. Fig. 3 is a sectional view through 33 of Fig. 1, Fig. 4 is a top or plan view of a modified form of blaze distributor to be used in ranges, cook stoves and the like and Fig. 5 is a sectional view through 55 of Fig. 4.

Similar characters of reference refer to similar parts throughout the several views of the drawings.

The main burner tube 1, super mixer 2, distributor 8, coil 4, feed pipe 5, gas valve 6, supply valve 7, damper support 8, damper 9, pan 10 and special burner 11, constitute the principal parts of my oil burner.

The main burner tube 1 is an ordinary pipe or tube and it is secured at one end in the damper support 8 and on the opposite e'reof is adjustably mounted the super the coil 4 after which it passes to the valve '6. through the pipe 4, support 4*, L 4 and connection 4% The support l is rigidly secured in one side of the damper support 8, which provides a support for the valve 6 for holding it properly positioned. The tube 1 is held in adjusted position in the super mixer 2 by means of a set screw 2. This super mixer 2 is a cupshaped member provided with an orifice 2 in one side thereof adapted for the tube 1. Mounted on the top of the blaze conductor 2 is a distributer which consists of the upper member 3 which is provided with a plurality of fine slots 3 adapted to permit the exit of theblaze and it is supported by a plurality of plates 3 placed one upon the other and these plates are provided with conforming lugs 3 and grooves'3 adapted for holding these plates in their proper relative position to each other. These lugs 3 however. are spaced apart leaving spaces between the adjacent plates to permit the blaze to pass out between the different plates. one of the plates 3 is mounted on a special plate 3 which is provided with an annular groove in its lower surface, adapted to fit the upper end of the super mixer 2 and it is provided with a cross bar 3 which is provided with a central hole adapted for the gas? Secured on the opposite-side of the damper support 8 f rom thesupport 4" is a T after filling the pipe 5 then igniting the fuel in the pan which is the proper method of starting the burner. Secured in the damper member-9 is a conductor pipe 9. which con"- ducts the gas from ltl'le regulating valve 6 to the proper position in the tube 1. ,The

damper is an annular: member fitting over the damper support 8,arid provided with segmental'opcnings adapted to admit air in an adjusted volu nie in the tube 1 to provide proper combustion.

In the" modified form of construction, shown in Figs. #iland 5 of the drawings there is provided an elongated blllr'lIlfl adapted for use in ranges and the like. downwardly extending is adapted to fit over the top of the super mixer2 and the blaze is distributed through the holes 11 as shown best in Figs. 4 and 5 of the drawings.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In a hydrocarbon burner amain tube, an adjustable air damper mounted thereon, a fuel conducting tube extending some distance into said main tube, a gas forming coil mounted around said main tube, a pluthe super mixer 2 from the annular portion 11 said mam tube, a burner mounted on the 60-... I

upper end of saidsuper mixer, and means for regulating the flow of gas from said coil to said conducting tube whereby the supply of fuel is regulated to said coil.

3. In a hydrocarbonburner a an adjustable air damper mounted thereon, a fuel conducting tube extending some distance into said main tube, a gas burner for heating said coil, a super-mixer adjustably secured on the extended end of said main tube, a burner mounted on the upper end of said super m i xerfeomprising a plurality of plates mounted one upon'the 65 burner mounted on. 40
